More specifically, walking involves alternatively swinging the sides of the rider's body forward and backward so that the rider moves with a stiff-legged walking motion. It is virtually impossible for the rider to cause the gyroscope to "walk", which is an upright motion useful for giving the rider an aerobic workout.
Forward bending at the rider's waist produces almost exclusive end-over-end motion of the inner ring, and negligible rotation on the vertical axis of the intermediate ring. A difficult and uncomfortable twisting motion about the vertical axis (which bisects the rider's body heightwise) is required. In this position, which will always be the start position of the gyroscope, it is very difficult for the rider to induce rotation about the vertical axis of the intermediate ring. The axis of rotation of the intermediate ring is vertical and 90° removed from the axes of rotation of the inner and outer rings. In the existing devices, the axes of rotation of the inner ring and the outer ring, when the rings are coplanar and the rider supported on the inner ring is in an upright position, are co-linear and horizontal.
